Я использую WSO2 EI 6.4.0
Я создал API, который будет вызывать внешний URL для получения информации. Ниже приведен мой код для API в WSO2 EI
<?xml version="1.0" encoding="UTF-8"?>

Я также добавил SSL-сертификат для URL-адреса токена , Может кто-нибудь, пожалуйста, руководство. Я могу получить URL-адрес токена от Почтальона. Я не понимаю, что может go здесь не так, так как это обычный API, и я ранее также использовал его для других URls.
Спасибо
